To all whom it may concer/n:

Be it known that I, Josnrrr LrzoTrE, a citizen of the United States, residing in Quincy, county of Norfolk, and State of Massachusetts, have invented an Improvement in Machines for Covering Studs; of which the following description, in connection with the accompanying drawings, is av specification, like letters on the drawings representing like parts.

The present invention relates to a ma chine for applying covering material to lacing studs and 'is embodied in a machine especially adapted'for covering lacing studs or similar articles, such for example as eyelets, with sheet celluloid which has been previously cut into pieces of the right shape and size to form a covering for the stud or eyelet. With the understanding that the several instrumentalities employed in connection With the machine may be designed for various specific pur oses, the invention is herein shown as embo ed in a machine esecially designed for covering'lacing studs or shoes, and the machine so designed 4Will be more or less specifically described in order clearly to illustrate the invention.l

In accordance with the invention the machine is provided with a die or a plurality of dies; cach adapted to support a piece of sheet celluloid and to conform the same, by

, pressure, to the surfacecofA a stud, eyelet or analogous article; the die o erating inconjllnctionwith a suitable ho ding device for the stud or eyelet to be operated upon. This holding device may be arranged so as to receive a stud or eyelet from a suitable feeding device by an automatic operation and to present the stud to the die the iece of celluloid having been previously. ed to the die so asto be interposed between the same and the stud. vThe machine is so arranged that? the sheet of celluloid thusheld between the stud and the die Will be heated to a degreesuiiicient to render the same pliable and t en will be acted upon by the operative elements of the machine in such a manner as to be shaped to conform to the outer surface of held in position after the material has cooled and become hardened. In the construction shown as an embodiment of the invention the machine is provided with a traveling member havin a plurality of operating devices for covering the studs, each of Which is arranged to be acted upon in the movement of the said traveling member so that the operative members Will perform the necessary operations consecutively during a s' le cycleof operations. Each operative'uglyement is complete in itself and is actuated by members which are stationar With relation to the traveling member W 'ch carries these parts, so that the machine may be provided With as many of said o` erative ele- JOSEPH LIZOTTE, OF QUlN-GYfMASSAOHUSETTS; MARIE L. LIZOTTE ADMINISTRATRIX OF andan automatic feeding device for suppliying'each diewith one of the articles to operatedupon; the covering material being previously supplied to the die in any suitable or usual Way. Each of the dies is prof vided with a crimping device herein shown as a sleeve concentric Withthe die and longitudinally movable With relationthereto so that when the sheet of covering material is held between the stud and the die the longitudinal movement of said sleeve Will ush the edge of the covering material beyon the edge of the article to be covered so that it Will stand substantially at a right angle thereto. The machine is further-provided With means for wiping or folding in this projecting edge of the covering material; such means being herein shown as a pair of Wipers arranged to move in a plane substantially parallel with the general plane of the surf ace to be covered, and to converge so as to dramvvY or Wipe in the projecting edge of the material previously bentand crimped by the sleeve aforesaid'.

It is desirable,l though .notessentiaL that themember tobe covered should be provided with a concave portion which affords a recess for the rough ed es of the covering material, and the machine may further be provided With means for forcing theedges of the material into such concave portion after the said edges have been turned or wiped over the edge of the stud.

Figure 1 is a front elevation of the ma chine embodying the invention; Fig. 2 is a horizontal section, showing the operative parts in plan view, with the parts above roken a'way.; Fig. 8 is a vertical section taken online X3 Fig. 2,' Figs. 4, 5, 6, 7, 8 and 9 are enlarged sectional details of the operative parts, showing the successive positionsv of said parts in carrying out a complete cycle of operations Fig. l0 is a sectional detail on a plane substantially at a right angle to that of Fig. 9, showing the partsm the same position as in Fig. 9; and Fig. 11 is a view similar to Fig. 10, but showingV the arts further advanced in the movement of t 1e traveling member. f f

While the machine embodying the invention may be adaptedfor use 1n covering any such articles as studs, eyelets, and the like, with sheet celluloid or other material, the

machine for convenience in illustration isv herein shown as es ecially adapted for covering with celluloi llacing studs for \shoes; and the invention will be specifically described in this connection, with the understanding that the invention is not to be limited solely to a machine designed for this particular purpose.

In accordance with the invention the machine is provided with a traveling member a, herein shown as a horizontal disk having a bearing u on a stud or projection A, around whic it-travels with relation to a stationary member B, which is provided with instrumentalities capable of causing the consecutive operations of the instrumentalities carried by the disk a. As herein shownthe disk a is provided with a gear a2 which is arranged to cooperate with a worm a3 so that in the operation of the machine the disk a will continue to rotate and to carry the articles to be operated upon, together with the operating devices which roduce the successive operations, causing t rese parts to travel with relation tothe coperatmg parts formed on the stationary member B. In the rotation ofthe disk a, the article to be covered, herein shown as a lacin stud, is received from a suitable feed-chute by a member b having a spring finger b2\which catches the shank of the stud; the said member b having a bearing in a sleeve b5 so that' it is capable of rotation therein. After the said member b has traveled past the chute C and has taken a stud therefrom, as best shown at the lower part of Fig. 2, the said member is turned upon its axis, that is to say, in the bearing sleeve b3 by the engagement of a tail or projection b4 with a member B2 upon' the stationary part B, so that the arm 1s swun to the position shown, at the left, in Fig. 2, t us carrying the stud into alinement with a die or plunger d carried by the disk a; the said plunger having a concave recess in the top substantially conforming in curvature to the convex surface of the stud. At this time, or prior to this time, the machine has been supplied with a disk of covering material such as sheet celluloid the said piece of material having been placed upon or overthe to of the die d. In the further movement o the disk a the arm b is lowered, the sleeve b3 which aords the bearing therefor being longitudinally movable with relation to the disk a and controlled in such movement, as best shown in Figs. 10 and 11,.by meansof a spring b5 together with its own gravity. The said sleeve b3, up to this period, is supported by means of a cam surface B3 upon the fixed portion of the machine, being provided, for this purpose, With a cam-roll 111; and as soon as the arm b has been turned so as to present the stud to the die it will be dropped by the disengagement of the roll b1 from the cam surface B3, and the piece of celluloid c, will be nipped between the stud and the die, as shown in 4. As the member a. continues to travel carrying the instrumentalities described beyond this poi'nt, the stud and the die with the celluloid held between the two 'will come under the influence of heat, applied for example by means of a hot air pipe D provided with jets D2, the heating being sufhcient merely to soften the celluloid and render the same necessarily reducing it to a p astio condition. The die d, which is herein shown as a vertically movable rod having a cup shaped end to correspond to the shape ofthe stud, is pushed upward by means of a cam d2 formed on the upper surface of the stationary member'B; the die being shown as provided with a rolld3 at the bottom. This upy ward movement of the die is suliieient to liable without it to the surface of the stud as indicated in Fig. 5.. AThe nextstep in the process is to bend or crim the edge vof the piece of celluloid so that 1t will stand substantially at a right angle to the edge of the stud as shown in Fig. 6. For this purpose the machine is provided ywith a crimping member e which is herein shown as a sleeve concentric with and surrounding the die d and capable of. longitudinal movement with relation thereto. As erein shown the sleeve e is connected by means of a pin e2 with a rod e3 having al cam roll e* in the path of which is a cam e5 which is beyond the cam d2; this cam acting to lift the sleeve e With'relation to the die, the said die beingshown as provided with a slot d* to receive the pin e2, and admit of the crimped 'by the action ofthe sleeve, afurf ther `independent movement of the die and sleeve talesfplace so that the crimped edge .will stand'beyond thel sleeve' ready to be actedfupon by a pair of wipers f, the purposegof1 which Yis to wipe in or fold over the projecting 'edge fof the celluloid until it has been turned past theedge of the stud.

herein shown the independent 'movement' above described is caused 'by giving the die d, a vfurther upward movement; this beingA accomplished through' the agency' of va' cam d5. s o situated as to produce this movement.

prior to the operation ofthe Wipers. Thewipers f are shown as consisting of a pairfof jawsplvotally supported upon a slide f2 which has'a cam roll f3 arranged to, vbe acted upon by camsf" and f 5 mounted upon a stationary part of the mach-ine in the posi tions shown in Fig. 2. When the cam roll f 3 engages the cam f i4 the slide f 2. is pushed forward, thefwiper jaws .at this dperiod being opened so aste travel past'an beyond the stud as indicated-in F1-ig." 7. The wiper jaws are opened and Vclosed respectively Vby means of pins -g y,and Ig? which are'mounted von a slide g3 which rests. upon the .slide f2y and is capable of movement independently thereof,

being shown as provided with a slot g4 which embraces the pivot j' 6 upon which thev jawsf have their bearing.- .'.The'slide g3 is provided with a cam roll g5 which coperates with a cam y, aftert-he jaws have-been moved forward, the said cam ge being in` a dierent plane afrom the camsf4 and f 5 so as to produce no effect on the slidef? The action of the cam g is such as to push the slide g3 outward, Vthereby forcing the pin g into contact lwith' inclined surfaces formed on the jaws behind the pivot, thus spreading the rear ends of the jaws and bringing the jaws proper together beyond the end ofthe stud. With the aus thus closed, the cam f 5 acts to draw the slide f2 backward so that the jaws f engage and vwipe in the projecting ledge .of the celluloid as shownin the Fig, 8. As herein shown the. jaws are provided with convex surfacesj."7

which,l when the jaws are brought together,A

form ra lrounded portion of suchjshape as to substantially .fit or conform td the surface ofV the stud over `whichthe crimpedand turnedin edge lies.,` In order to force thel said edge into'closez contact with thefstud the die d is given slight furthen upward movement through the agencyA-offa @amd6 .thus pressing thestud up intoclo'secontfact with thej'aws.. and forcing the edge lof v'the celluloid to the position. shown in 9.r1

The

wiper jai.F s f are then opened through the i agency of thepin g2 and the slide g3, the pin g2 acting upon inclined surfaces formed onV the viper jan s in front of t-he pivot f6. To accomplish this the cani roll g5 is acted upon by a cam surface'gr7 which produces a rearward movement of the slide g3 to Open the jaws, thereby releasing the stud, which then rests between the. die d and the stud holding device b. 'lheslide-f2 is then acted upon'by a cam f8 which wit' draws the entire vfiper member to the position shown at the bottom part of Fig. 2. In order 'to release the stud the stud-holder is lifted from the position Ashown in 10 to the position shot-.n in

Fig. 11, through the engagement of the cam surface b by the roll bw. The die is also lowered at about the same time, through the agency of the cam surface (i7, and the stud is kleft in the stud-holder, freel of the die and cooperating parts, as shown in l1. In the further progress of the traveling member a, the studeholder is turned on its axis by the engagement ofthe tail b9 'with the stationary projection b?, so that it finally stands in the position inv which it is shov-.nat the bottom of Fig. 2:v is caused to dip and rise, by means of the cam surface 68, and in the dipping movement.
